Given the fragility of the 3rd generation "Kindle" screens, a stiff case can make all the difference. This design can serve as a template for your own custom case (see my showroom photos for some examples of text and illustrations for engraving), and can also be used as a notebook case, etc. The design features some wiggle room, I use cork to hold the device firmly in place without rubbing the screen on the case.
I designed for a snug fit, erring cautiously to avoid the material tolerance causing the slots to be too small for construction, so a few minutes of sanding will speed along the construction process.
I cut this in 2.7mm bamboo, but you're welcome to try other materials. . .<br></br><img alt="Kindle3casesidesmall1_showroom_image" src="http://static3.ponoko.com/design_images/images/84564/1e6d13ad-166a-6f41-6fd0-48f9e20b60ac/kindle3casesidesmall1_showroom_image.jpg?1395801976" />Wed, 26 Mar 2014 03:00:24 GMThttp://www.ponoko.com/showroom/theBilder/11452?time=Wed+Mar+26+02%3A17%3A15+UTC+2014theBilderP2 Kindle 5 Casehttp://www.ponoko.com/showroom/theBilder/11453

This P1 design will help anyone seeking to up their game when it comes to working with smaller tolerances! Take the design and apply it to your desired material--and when it's done, you'll have a unique set of laser cuts that will help you determine how to account for the nuances of the material you are working with.
I recommend using a micrometer or caliper measuring these tests, as we're working with very small numbers :).
Includes:
All tests have labeled parts for easy measurement comparison!
Laser Kerf (Radius) - Measure the cutouts and holes to find specific values for how much material the laser burns away. (Printed Value - Measured Value) / 2 = Laser radius. This is also equal to how much to "expand" your designs before cutting to retain size.
Minimum Feature Size - (If you want make smaller features than the 1.0mm recommended size!) Pop the cutouts out and measure each descending prong until you find one that suits your project. (Note the smaller prongs will either be completely burned away or fused, this is intentional as anything that breaks is too small to include in your design.)
Minimum Distance Between Cuts - Find out how close you can go between cuts before burning or fusing the material away - useful for perforating and setting up design 'tabs' to attach larger pieces to the sheet of material for safer shipping.
Bonus: Water Absorption - There's a little bit of talk that acrylic can absorb water and change size if submerged (admittedly by a very small amount, think 1-2%)! If you're worried about how environmental conditions might affect your design, pop one in water for 24 hours and compare it's dimensions to the other to see if there's any change.<br></br><img alt="P1_test_array_2017" src="http://static1.ponoko.com/design_images/images/164967/3e0a46ae-5a21-39e6-0dba-461eaaeddd85/p1_test_array_2017.7.28_no_border-01_showroom_image.jpg?1501871720" />Fri, 04 Aug 2017 18:42:29 GMThttp://www.ponoko.com/showroom/BenHoaglandsWorkshop/14373?time=Fri+Aug+04+18%3A11%3A58+UTC+2017BenHoaglandsWorkshop
